Overview
FastAPI Boilerplate packages the project structure and operational defaults repeatedly needed for production Python APIs.
A Useful Starting Point
The starter separates routers, middleware, models, dependencies, database wiring, internal helpers, and utilities. It provides a clear place for each concern without forcing an application-specific domain into the template.
Predictable Responses
A shared response model keeps status codes, messages, payloads, error codes, timestamps, and success state consistent. Route handlers can return the same envelope without rewriting formatting and metadata on every endpoint.
Local or Containerized
Poetry manages the Python 3.12 environment and Docker Compose provides a second, repeatable path to run the API. Pydantic v2 and Uvicorn complete a small stack that is easy to understand before extending.
AI Ready, Not AI Locked
Optional helpers for LangChain, Ollama, OpenAI, embeddings, and model access came from its original quiz-master use case. They stay isolated from the core API structure, so a conventional service does not need to adopt the AI layer.
